*i This invention relates t'o improvements in the type of machine shown in the patent to J. P. Gardner, No. 1,305,595, June, 1919." The patented machine was designed so that it required anfattendant or operator to operate the same, the patient or person being treated `having but little actual control ofk the machine. 4This was found in actual' use to be somewhat objectionable and the l,present machine is designed so that it may be operated by the patient. v v f The objects of this invention areto `provide an improved massage or body treatment machine of the character., indicated; to provide a machine of .this character, all `ofthe functions of which may be controlled or operated byy the person beingt-reatedin the machine; to provide an yimproved arrangey ment for supporting andguiding'the roller 2G supporting chains;ltov provide an improved locking device for locking the lchain adjusting arms`; to .provide an improved arrange-A ment for adjusting the tension on the chains;

to provide an improvedr frame and means for supporting a platform therein; to provide "an improved'covering forv the top of the frame,

to provide an improved chain and motor construction; aiid to provide such other` novel features and improvements. as lwill appear from the following description. y

Figure 9 is a section taken on the line In the particular vided with a frame 10v which is preferably form ofthe invention .asl shown in these drawings, :the machine 1s 'prof made in sections, as shown, for convenience in manufacture, shipping, and installation.k

`The base or lower portion of the frame vhas ymost of the-operative parts fare mounted.

The upper horizontal member 13is provided with a covering 14 of cork or cork composi- 65 tion. or other; suitable material on which the patient may restv hisarms. Two driving shafts'V 15 and 16 are mounted atthe back of the frame and arev driven by any suitable driving mechanisin.- These shafts may be driven in either the same or opposite directions, maybe driven continuously in either direction,.or may be oscillated or reversed in order to give diferentmovements to the massaging devices. In the present instance,` these shafts are provided respectively with worm gears 17 and 18,*(Figure 6) which aredriven byv a common ,worm 19Y which is mounted on a shaft 2O having ka pulley 21 which ,is driven by a belt 22 fromV a motor 23. v:The 89.A

' driving gears are mounted inv a housing'24 Y on the main frame, which is adapted to retain' oil or grease for lubricating these parts. The

; motor may be of the reversing type in order 27 engage "with the sprockets 25,and ytwo other chains 28", 28 engage'with the sprocket 931 wheels 26. VThe chains 27 passt aroundr three other sets of sprocket wheels29, 30, and'Bl.

` The chains 28 passaround three-other sets of sprocket wheels 32,33, and'34. The sprocket 9,5 wheels 29 and32 are respectively carried by arms 35 and 36 which are securedto shafts.

f which 'they may te Swingin Order to 'press Inordertof provide a `constant Vtension on the chains, a rope or cable 41 issecured tothe .outer ends ofthe arms39 and 40 and passes overrg'uide wheels or: pulleys 42 and 43 and is engagedr by ajcentral pulley 44,5(Figures 1k and 3) The pulley 44 is ffmounted at the lower end'of a tube` or'pipe 45 (Figure 5). which has a disk 46 secured thereto for supporting a weightf47.

Vso'fgpropo'rtioned in 1 'y length and arranged,l at such fan angle to the Vwill 'ftake substantially all ot the slack arms 59 and60 lthat vthesprockets 30 land 33 which Amay* be duefto the swinging of the sprockets 3l andk34,1 or in otherwords so that e therefwill "be `littlelor no 'change in the .ten`

sonfn the chain due tothemovement of these sprockets.4 A f The various sets of guidesprocketsare secured to shaftsfwhich are-,mountedk in-bear# ings at the outer ends of thearms, as shown particularly in Figure 7 and these bearings are preferably provided with protecting disks or flanges 6lzwhich are adapted to prevent the patient from accidentally sticking his lingers into the sprockets.

E In order to sw'ng the arms 59 .and'60vwith the parts connected therewith,' I vprovide Y handles 62 and 63 which are carried on pins 64 and 65 whichrproject upwardly Vfrom the bearngs5as'shown in Figure 7. These parts are locked in position by locking arms 6,6l and 67- Which have holes at their outer ends lfonengagement with Vthe pins 64 and 65 and which are bifurcated 'at their inner ends `for ,engagement-with the shafts 57and 58. The lockingarms are provided 'with pins or projections 68 and 69v which are adapted toengage respectively withseries of holes 70 and 71 in-plates or segments 72 and73 which project outwardly from vthe lupper portion of the main frame The outer ends 'of the arms 66 and 67 are held'innormallyV raised position by springs 7 4- and 75. LVVhen theepatient desires to swing the arms toadjust the chains, he presses down on the "handles 62 and'V 66 which releases the pins or catches 68 and 69 and thenswings-'the armslwith'the parts connected therewith tothe desiredposition and releases the handles 62`and l63, 'whereupon thelprojections 68 and 69 will again enter the holes in the segments to lock. the :parts inadjustedposition. s'

' The chains are provided'at intervals with brackets or projections76-(Figures 8 and 9) which carrythe rollers 77. V'Ihese'rollers or massage devices may be :made oi-` any suitable material yand mounted yon the chains in any desired mannen :but in the present `instance rodsorpintles 78 are secured to the projece v80 which extend out belowthe lower ends of the. rollers (Figures l and 3) and 'tend to support the rollers in thexevent that the ,chains become slack and thereby prevent the chains from disengaging thesprockets. They also serve as a further protectionto prevent the patient from inserti-ng his fingers between the lower 'chains and` sprockets; e In the Voperation of Vthe machine,` the pa-V tient may remove the platform and stand on the'ioor-.or-may adjust theplatform and standor sit7 or otherwisedispose of himself l and guide sprockets.

convenient position so that the patient may j start the machine either beforey getting into it or after adjusting the same. In some instances, the arms at the front of the machine are swung inwardly, yas shown in dotted lines in Figure 1, so that the opposite reaches of the massage belts or chains substantially encircle the body, as shown indotted lines in Figure 1. During such adjustment the weight 47 acting through the cable il and the arms 39 and 40 will tend to hold the arms 35 and 36 so that the sprockets 29 and32 will press against the chains 27 and 28 and hold them closely in engagement with the driving When the opposite reaches of the chains are curved around the sides of the body, the tension on the chains and consequently the pressure of the massage devices against the body may be increased to any desired extent by turning the screw 49,

as heretofore described.` The machine isv adapted for giving, various kinds of treatment and for massaging different portions of the body, but as the use of suchv machine is well understood at the present time, further description is not necessary. l s
